QUALITY

What should I ask?

Learn current colonoscopy quality measures and questions to take to a practice.

Before scheduling

Call with a short checklist.

Is the physician/facility in my insurance network? Is this being scheduled as screening, surveillance, or diagnostic evaluation? Who provides sedation/anesthesia, and are they in network? Which pathology laboratory is used, and is it in network? Does the practice track colonoscopy quality measures? How do I get help after hours if I have a post-procedure problem?
